REVOLUTION-COUNTER.

Specification of Letters Patent.

Patented Feb. 13, 1917.

Application filed August 14, 1914. Serial No. 856,833.

To all whom it may concern Be' it known that I, VVI'LFRID PAUL HEATH, acitizen of the United States, residing at St. Paul, in the county ofRamsey and State of Minnesota, have invented certain new and usefulImprovements in Revolution- Counters, of which the following is aspecification.

An object of my invention is to provide a mechanism which may beattached to a revolving part to count a certain number of revolutions. 1A further object is to so construct the parts of the mechanism that thenumber of revolutions to be counted can be varied at the option of theoperator.

A still further object is to provide an alarm means constructed as apart of the mechanism and which will be sounded upon the completion ofthe predetermined number of revolutions.

lVith other objects in view, which will be referred to, my inventionconsists in the peculiar combination and novel arrangement of parts,such as will be hereinafter more fully described in connection with theaccompanying drawings and more particularly pointed out in the appendedclaims.

In the drawings Figure is a view in elevation of the mechanism.

Fig. 9. is a View in end elevation of the disclosure in Fig. 1.

Fig. 3 is a transverse sectional view on the line 3+3 of Fig. 1. j

Fig. 4 is a longitudinal sectional view on the line 4-4; of Fig. 1.

Fig. 5 is a fragmentary detail view of the screw threaded shaft and ofparts lootiperating therewith.

In creameries where it is desired to give a predetermined number ofrevolutions to the churn to mix thesalt in the butter and in otherconnections where it is desired" to announce when a predetermined numberof revolutions have been given to a rotatably mounted part, it has beencustomary to gage the number, of revolutions by a separate mechanismconnected to be actuated by the rotation of the parts and to remain at afixed point during the rotation of the parts, however, with such amechanism a distinct operation and movement is required to bring part ofthe operator who may neglect to set the counting mechanism to theoperative relation, therefore my invention is devised to be placed uponthe revolving parts, as for instance upon the churn adjacent the doorand will thus be accessible to the operator when other of the parts ofthe mechanism are adjusted, further by, securing directly to therevolving parts the operation is mad more sure and positive.

My mechanism comprises the bracket members 1 and 2 which are connectedtogether by the rods 3 and 4'to be spaced apart, and the slide rod 5 andthe gage rod 6 are mounted between the bracket members 1 and 2 to extendparallel with the rods 3 and 4. The screw-threaded shaft 7 is revolublymounted in the bearings 8 and 9 provided in the bracket members 1 and 2and this shaft 7 extends parallel with the slide rod 5 and the gage rod6 and is preferably spaced equidistant between the two.

The bracket members 1 and 2 are provided with the opening 10therethrough by which they may be attached to the revolving parts, therevolutions of which are to be counted, and the eccentrically mounted vWeights 11 are secured on one end of the screw-threaded shaft 7 to causethis shaft to be given one complete turn upon each revolution of theparts to which the mechanism is attached.

A slide bearing 12 is mounted on the slide rod 5 to have free endwisemovement and this hearing 12 has an arm 13 formed to extend radiallytherefrom and provided with a spring clip 14 which may be brought toengage over the gage rod 5 by exerting pressure upon the arm 13. The arm13, at a point adjacent the disposition of the screw-threaded shaft 7has a half nut 15 secured thereon and the threads of this half nut areof a pitch to engage with and turn in the threads of the shaft 7 thus asthe arm 13 is swung to a position that the spring clip 14 is engagedover the gage rod v6 this half nut is brought to a position with thethreads thereof meshing with the threads of the shaft 7 and therevolution of the eccentrically mounted weights 11 will cause bracketmember 1 to a position between the bracket members 1 and 2. A curved arm18 is secured on the slide bearings 12 and as this bearing is movedalong the slide rod 5 by the feeding of the teeth of the half nut 15along the thread of the shaft 7 causes thls arm 18 to engage with theoperating stem 17 and actuates the bell to permit the sounding of thealarm and the enunciation of the fact that the requisite number ofrevolutions have been' completed.

The gage bar Ghas a scale indicated on the upper side thereof to showthe number of complete turns of the threads around the shaft 7 and thisscale 19 is graduated along the length of the gage rod to permit theset- 1 ting by the operator of the arm 13 and the screw-threaded members15 carried thereby to be moved along the extent of the screwthreadedshaft 7 and to operate the alarm pon thercompletion of any number ofrevo- 1 uti'onsof-this shaft 7 through the movement ofitheeccentricallymountedv weights 11. A

' gage collar 20 is mounted on the gage rod 6 to be capable of endwisesliding movement and-a set screw 21 1s provided'to set this collar thedesired point and to per mit tlie'abutment of the arm 13 and the springclip 14 thereagainst to gage a predetermined set number of revolutionswithout the necessity of a manual setting of the arm 14 for eachconsecutive operation of the mechanism.

"From the foregoing it will be seen that I have provided a mechanismwhich may be attached to and carried by a revolving part i to count apredetermined number of revplutions of the part and which may be set tovary the number of revolutions counted, further which causes theoperation of an alarm to announce the completion of the predeterminednumber of revolutions and which maintains the alarm until manually cutoff, which cutting off requires a stoppage of the revolving pait. Stillfurther it will be seen that the mechanism is'composed of but few partswhich are simple in construction and manufacture and which accomplish astruc ture efficient and. positive in operation and presenting verylittle. likelihood of disarrangement or displacement of the parts.

WVhile I have herein shown and described one specific form of myinvention, it will be understood that slight changes might be made-inthe form and arrangement of the several Without departing from thet'iopiesof this patent may be obtained for five cents each, byaddressing the spirit and scope of my invention, and hence I do not wishto be limited thereto except for such limitations as the claims mayimport.

I claim 1. A revolution counter comprising a pair of brackets to besecured in a fixed relation on the revolving part, a screw-threadedshaft mounted to have turning movement in said brackets, means totransmit a complete tiirn to the shaft upon each complete revoluti on ofsaid revolving part, a gage rod hav ing a scale thereon arrangedparallel with the screw-threaded shaft and marked off in designationscorresponding to the number of threads in various lengths of the shaft,a gage member provided with a screw-threaded portion to mesh with thethreads of said shaft, and means to be engaged over the gage rod to holdthe gage member in indicating relation with respect to the markings onthe gage rod and to also hold the screwthreaded portion thereof inproper mesh with the threads of the shaft. v

A revolution counter comprising a pair of brackets to be secured in afixed relation on the revolving part, a screw-threaded shaft mounted insaid brackets to be held against endwi'se movement and to be capable ofturning movement, means to cause turning of the shaft as the revolvingpart is turned, a gage rod mounted between said bracket members toextend parallel with the thread ed shaft, a gage member provided with ascrew-threaded portion to mesh with the threads of said shaft mounted tobe capable oftraveling movement along the extent oi the screw-threadedshaft, aspring member connected with the gage member to be fitted overthe gage rod to hold the gage member in indicating relation with respectto the markings on the gage rod and to maintain the screw-threadedportion thereof in mesh with the screw threads of the shaft, and anadjustable member mounted on the gage rod to be moved and set atpredetermined markings thereon to permit quick and repeated adjustmentof the gage member to count a predetermined number of revolutions of thescrew-threaded shaft.

In testimony whereof I aiiix my signature in presence of two Witnesses.
